Description

Create an Excel file using LotusScript without MS Excel OLE installed on PC. Solution is based on Java Apache POI 4.1 https://poi.apache.org/ (with LS2J example).

There are 2 libraries and 1 agent in demo database:

1. Apache.POI-4.1 - contains Apache POI jar. They can be found on poi.apache.org so you are free to upgrade it if newer version appears.
2. Apache.Excel - provide a Class we can re-use in LotusScript using LS2J approach. So far it contains only basic methods (but for simple reports it's enough).
3. Demo - agent that shows how to use Apache.Excel library via LS2J.

Example of agent

Option Public
Option Declare

UseLSX "*javacon"
Use "Apache.Excel"
